Power Play is an interactive activity that helps you learn about harnessing energy from different power sources. Click on the start icon to begin the activity. The four different screens in this interactive are divided into an upper and lower section. In the upper section, there is a picture of a power source on the left and a picture of a job that needs to be accomplished on the right. In between these two pictures is a blank space that you should fill up with the parts to build a machine that would capture the energy from the power source to get the given job accomplished.
You are given machine pieces (plus others) in the lower section in order to build the appropriate machine in the upper section. To build the machine, click on one of the parts in the bottom screen and then drag it into the upper screen. Each machine requires three pieces. Once the machine works, click "Next" to go on to the next challenge. To make it more fun, try to do this as fast as possible!
In the lower section, on the far right, there are three icons that you can click on to get more information. The "!" takes you to a screen that contains information about energy; the "?" takes you to a screen that gives directions about how to play the activity, and the "Done" button allows you to quit the interactive.
